- llat To all whom it 32 concern:
Be it known that l, WILLARD 1E. Swm'r,
a citizen of the United States, residing at Worcester, in thecounty of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in indow-Envelops, of which the following is a specification accompanied by drawings fong a part of the e.
My present invention relates to that class of envelops hire as window envelops, or envelope in which means are provided for disclosin the address upon the inclosure Ml within the envelop. in this class of envelope an opening is usually formed in the body portion of the 'envelo through which the ll may be read.
is mmetimes covered with transparent aper plied to the inside of'thc envelop efore rh blank is folded, or, in lieu of an opening a sion of the body portion of the envelop is rendered transparent by appl ereto some oleaous terial.
The obj of my present invention are to enable the lower fold or edge of the inclosure to serve as a for the address which ma be or written in pronimity to t e lower edge of the inclosure as the se is folded for insertion in the envelop; to facilitate the nipulation of letters, in trassion through the mails; a n p 2 i :1 l esion of the tra parent patch when applied to cover the ope a" in the body portion of the envelop. as objects ll accomplish by the construction and arrangement of parts as hereinar describ and illustrated in the aci i. 2 reresents the blanlz in e nded or M which the envelop is me n Ill the position of the window, an illustra by broken lines, the folded pr sition of the end flaps and back dap.
Fig. 3 is a central sectional view of a com le envelop shown on the ple of the roken line Fig. l.

portion of the envelop and covered b a patch of transparent paper 4, in out ine substantiallfy like the openin 3, and represented in ull in Fig. 2. he envelop l is formed of a blank shown in extended form in Fig. 2 and comprisin a seal flap 5, end flaps 6, 6, and a back dap 7. The blank is folded upon the broken lines 8, 9, l0 and 11 inclosing a rectangular space which forms the body portion of the envelop and upon which the end flaps 6, 6, and back flap 7 are folded, as represented tion of the envelop and the back flap is folded over the end flaps, to which it it united at its overlapping edges M, 14, in the usual manner.
Before the envelop is folded, the opening 3 is formed in the body portion of the envelop, which in the present instance is ,covered by the transparent patch 4L, attached to the blank by a narrow stripe of gum, preferably applied to the blank aroun the openin 3.
"lhe above described method of constructing a window envelop corresponds with that now practised with the exception that the o ening 3 is formed at some distance from t e lower edge of the envelop, so that a narrow strip foin the body portion of the etween the opening and the line of fold 11 between the body portion of the envelop and the back flap. ln providing an address upon the folded inclosure it is necessary that the osition of the address be made to register th the opening 3, preferably in the center of the opening. This ll ll tion of a window envel in which a a: e
patch a i in the failure to cause a close ill of the transparent atch close to the edof the opening. l it causes a pocket or space between the ed of the openin and the trarent la catch t e corners of envelope as they ther in the oary manr ation of letters, in a imion throng the mails e g is plac at some we are e low of the envelop are The
is appli to cover the openme i increases the liability of the corners of letters being caught therein.
f My present improvement consists in forming the window with its lower edge coincident with the line of fold 11 between the body portion of the envelop and the back flap. When the line of fold of the inclosure has been determined the address may be applied to the inclosure with definite reference tothe line of fold of the inclosure, said line of fold of the inclosure always corresponding to the lower edge "of the window, and also with the lower edge of the envelop. This enables the address to be applied tothe inclosure in exact position for-its proper registrati n with the window. i
W on the window is formed by an opening 3 covered by a transparent patch 4, a pocket, 38 above described, can only be formed upon the upper edge of the window, as any ungummed space around the lower side of the window opening between the envelop and the transparent patch will occur on the back side of the envelop, for the reason, that the lower edge of the patch 4 is applied to the back flap 7 and not to the body portion of the envelo i As represented 111 Fig. 2 the entire lower folded upon itself and reof folding, thereby giving greater security to the attaehnient ofthe transparent patch.
It will thus be seen "that the envelop formed as above described, provides an inclosure pocket, having a window in the front wall and having its rear wall constituted by the folded flaps of the blank, with one side of said window substantially coincident with the line of fold between the front wall and the back flap.
I claim 1. An envelop for an address bearing inclosure, wall, one of said walls having a window opening therein, with the edge of said opening substantially coincident with the line of fold between said walls, at the bottom of the envelop,-and a transparent patch attached to comprising a front wall and a rear the inside of the envelop to cover-said open- 1 ing and all sides.
2. An envelop for an address bearing inclosure, comprising a front wall and a rear wall, one of said walls having a window opening therein, with the edge of said opening substantially coincident with the line of fold between said walls, at the bottom of the envelop, and a transparent patch covering said opening, said patch having a fold corresponding to the fold between said walls, and being attached to each wall on opposite sides of its line of fold.
